In 2022, we purchased a 1950 M-System trailer in original—but very rough—condition from a couple we met at a rally in Red Bluff, California. While it had great bones, it needed a full restoration from top to bottom. After two years of planning, we rolled up our sleeves and brought this vintage gem back to life—It was completed just in time for its debut at the 2025 Palm Springs Modernism Week Vintage Trailer Show in February, where it won the Best of Modernism Award! It is now for sale and could be yours.
The Restoration Process
We began the restoration on the exterior, replacing all of the aluminum siding. Much of the wood framing—especially near the bottom—was rotted and had to be rebuilt. We also updated the insulation, electrical, and plumbing systems.
For the exterior look, we decided to paint the top and bottom panels and polish the aluminum band around the center. We restored all the window frames, replacing the rubber seals and glass, and even updated the Hollywood windows with new Plexiglas. Most of the marker lights, taillights, and hardware are original and in excellent condition.
Underneath, we replaced the axle, wheels, tires, and brakes. We also installed new propane lines, a tank, and a custom tank holder to round out the exterior upgrades.
A Fresh Take on the Interior
Inside, our goal was to preserve the trailer’s original character. We refinished the beautiful birchwood paneling, restored the floors, and refreshed both the vintage refrigerator and stove. In the rear bedroom, we added a new full-size mattress, and in the living room, we installed a queen-size sleeper sofa.
The bathroom, originally made of aluminum and equipped with a toilet, sink, and shower, got a slight layout change—we removed the sink to free up some space and installed a new toilet and shower fixture. Although this is a park model that requires full hookups, we added a small black tank for added convenience. To brighten things up, we painted the entire bathroom a glossy white, giving it a clean, fresh feel.

Worth the Effort
The full restoration took about eight months, and we couldn’t be happier with how it turned out. It still feels true to its original Art Deco design, but with all the comforts and style updates needed for modern use. To top it all off, our M-System trailer was featured in issue 79 of the Vintage Camper Trailers Magazine and honored with a Best of Modernism Award at the 2025 Palm Springs show—a moment we’ll never forget.
